目的 :探讨对虾中肠腺脂肪酸与病毒病之间的关系 .方法 :应用气相色谱法分别检测了人工养殖的健康斑节对虾、健康日本对虾、斑节对虾杆状病毒 (MBV)轻度感染斑节对虾、MBV重度感染斑节对虾及患中肠腺坏死杆状病毒 (BMNV)病日本对虾中肠腺脂肪酸的组成及含量 .结果 :养殖健康斑节对虾中肠腺中的饱和脂肪酸以棕榈酸为主 ( 2 0 64% ) ,一烯酸以油酸含量最高( 2 3 0 7% ) ,多烯酸则以亚油酸所占的比重最大 ( 2 1 72 % ) ,这 3种脂肪酸的总量达 65 4 3% 健康日本对虾中肠腺饱和脂肪酸仍以棕榈酸为主 ( 11 10 % ) ,一烯酸则以二十二碳一烯酸含量较高( 15 2 3% ) ,多烯酸以二十二碳六烯酸含量较高 ( 9 91% ) ,这 3种脂肪酸的总量为 36 2 4 % 与斑节对虾相比 ,日本对虾中肠腺脂肪酸各种成分的分布较均衡 MBV重度感染斑节对虾中肠腺各种脂肪酸的含量均有异于健康虾 ,患病日本对虾中肠腺各种脂肪酸的含量也出现明显的变化 结论 :患病对虾中肠腺脂肪酸代谢障碍
Objective: To investigate the relationship between visceral gland fatty acids and viral diseases in shrimp midgut.Methods: The healthy infected Penaeus monodon (Penaeus monodon), Penaeus monodon (MBV) The results showed that the saturated fatty acids in midgut glands of P. monodon were cultured with palmitic acid (2064%), the highest oleic acid content (2030%) for monoenic acid, and the highest proportion (21.72%) for linoleic acid for the polyenoic acids Total amount of 65 4 3% Saturated fatty acids in midgut gland of healthy Japanese shrimp were still dominated by palmitic acid (11 10%), while monoacidic acid was higher in docosahexaenoic acid (15 23%) and more The higher levels of docosahexaenoic acid (9 91%) for the alkenoic acids and the total amount of these 3 fatty acids were 36 2 4%. The distribution of glandular fatty acids in shrimp Equilibrium MBV Severe Infections The content of various fatty acids in midgut glands of Penaeus monodon varied from healthy shrimp to diseased Japan Shrimp midgut gland content of various fatty acids were also significant changes Conclusions: The prevalence of shrimp midgut gland fatty acid metabolism disorders
